'''Z80''', <br/>
an 8-bit [https://en.wikipedia.org/wiki/Microprocessor microprocessor] designed by [https://en.wikipedia.org/wiki/Zilog Zilog] founder and CEO [https://en.wikipedia.org/wiki/Federico_Faggin Federico Faggin], first released by Zilog in July 1976. It was designed to be binary upward compatible with the [[Intel]] [[8080]] so that most notably the [https://en.wikipedia.org/wiki/CP/M_operating_system CP/M] operating system would run unmodified, but offered an enhanced instruction set, two separate register banks plus two additional 16-bit index registers IX and IY.

The 8080 compatible registers AF, BC, DE, HL are duplicated as two separate banks in the Z80 <ref>Z80 architecture, by [http://commons.wikimedia.org/wiki/User:Appaloosa Appaloosa], October 17, 2007, [https://en.wikipedia.org/wiki/Zilog_Z80 Zilog Z80 from Wikipedia]</ref>
=Endianess=
Like [[8080]], Z80 is a [[Little-endian|little-endian]] machine, concerning the [[Byte|byte]]-order of 16-bit [[Word|words]] in memory.
